2 Claims.

My invention relates to a new and useful improvement in a gauge mounting adapted for use in mounting a gauge or indicating device on a lathe, milling machine, or similar structure. The mounting is intended for use with gauges and indicators used for indicating external dimensions or diameters. It is an object of the present invention to provide a mounting which will give a maximum degree of flexibility so that a universal movement of the gauge or indicator may be accomplished.

It is another object of the invention to provide a mounting so arranged and constructed that the gauge r indicator will be used in all positions or locations in which it is necessary that the same be used so that no removal and replacement of the gauge is necessary.

Another object of the invention is the provision of a mounting of this class which will be simple in structure, economical of manufacture, durable, and highly eflicient in use.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood from a reference to the accompanying drawing which forms a part of this specification and in which,

Fig. 1 is a side elevational view of the mounting with parts shown in section.

Fig. 2 is a front elevational view of the mounting with parts broken away.

Fig. 3 is a top plan view of a slightly modified form of the invention with parts shown in section.

Fig. 4 is taken on line 4-4 of Fig. 1.

In Fig. 1, I have shown the indicator H with a contact point l2 projecting outwardly therefrom. Extending down from the base of the indicator I is a boss |3 through which extends the bolt I4 on which is threaded the nut l5 whereby the indicator may be mounted on the boss l5 and swung to various positions as shown in dotted lines in Fig. l on the bolt H as a pivot. This boss or standard l6 projects upwardly from the ball H which rests in a socket formed from the recess l8 in the block l9 and the recess 20 in the cap 2|. This block I9 is positioned in the cavity formed in the head 23 and cap 2| is threaded thereon. Spring 24 positioned'in the extension 25 of the head serves to force the block l9 upwardly so as to maintain a close bearing on the ball [1 and prevent any undue movement of the same. The structure is such, however, that the plate or standard l6 may be rocked to various positions s shown in dotted lines in Fig. 1 and in Fig. 2. Thus a universal movement is eflected through this connection.

The head 26 is mounted on one end of the rod 21. This rod passes through a supporting sleeve 28 and may be slid longitudinally therein. The set screw 29 serves to lock the sleeve 28 in various positions on the rod 21. Projecting downwardly from the sleeve 28 is a supporting standard 30 connected to which is a bolt 3|, the bolt 3| is provided with the neck 32 having the threaded socket 33 for the reception of the threaded neck 34. This bolt 3| is engaged by a block 13" pcsitioned in a head 26" and forced by the spring 24 upwardly toward the retaining cap 2|. In this regard the structure is the same as the support connected to the end of the rod 21. The rod 21 may be tilted and universally moved on this mounting as will be obvious and the head 26' may be attached to a milling machine, or lathe tool post in desired manner. In Fig. 3 the head 26 is illustrated as being connected to the rod 35 which projects through the clamping sleeve 36 mounted on the collet 31 and movable in rockable position by the jam nut 38.

It is believed obvious that with a mounting such as I have described universal movement of the gauge becomes possible and considerable economy in operation is effected by virtue of the fact that the same does not have to be dismounted and remounted for various types of jobs.

The invention, including all of the parts connecting the gauge H with the rod 21, may be used as standard equipment on all service plates as the standard sliding blocks are all equipped with an upstanding rod having a sleeve for the reception of the rod 21. It is also believed obvious that the mounting may be used for other purposes than merely mounting a gauge as the construction may be used wherever a universal movement of this kind is desired.

While I have illustrated and described the preferred form of my invention I do not wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In combination with an instrument casing, a head; a rod connected at one end to said head and projecting outwardly therefrom; a pressure block slidably mounted in said head and having a semi-spherical recess in its upper face; a cap threaded on said head and having its inner surface recessed, and forming, with the recess in said block, a spherical chamber; a ball positioned in said chamber; a standard secured to and projecting outwardly from said ball through an opening formed in said cap; a lug on the casing; means for pivotaily connecting said lug to the outer end of said standard; means in said head for pressing said block against said ball and preventing undue movement of the same; and means for mounting said rod intermediate its ends for universal movement.

2. In combination with an instrument casing, a cup-shaped head; a neck projecting outwardly from one side of said head; a rod engaging at one end in said neck and serving as a support for said head; a pressure block slldably mounted in said head and having a semi-spherical recess in its upper face; a spring positioned beneath said pressure block and the bottom of said head for normally forcing said pressure block upwardly, said head being recessed at its bottom to a point below the center of said rod for accommodating said spring; a cap threaded on said head and having its inner surface recessed and forming, with the recess in said block, a spherical chamber; a standard secured to and projecting outwardly from said ball through an opening formed in said cap; a lug on the casing; and means for pivotally connecting said lug to the outer end of said standard, the pressure of said spring normally resisting movement of said ball in said chamber.
